ABSTRACT:
A reed relay includes a reed switch with contacts, and a pair of terminals connected to the contacts. A tubular electrostatic shield defines an axially extending central bore within which the reed relay is inserted. A coil assembly has a winding drum, and a coil provided on the winding drum. The winding drum defines an axially extending central bore within which the electrostatic shield is inserted with the reed switch. A first pair of leads extend oppositely to each other, and are connected to the electrostatic shield at the opposite ends of the coil assembly. A second pair of leads extend oppositely to each other, and are connected to the electrostatic shield at the opposite ends of the coil assembly. A third pair of leads extend oppositely to each other, and are connected to the coil at the opposite ends of the coil assembly. A fourth pair of leads extend oppositely to each other, and are connected to the terminal of the reed switch at the opposite ends of the coil assembly. The fourth pair of leads being disposed between the first and second pairs of leads.
